  • 65 Possibly Lost Orchid Treasure of Bangladesh
    J. biodivers. conserv. bioresour. manag. 3(1), 2017 POSSIBLY LOST ORCHID TREASURE OF BANGLADESH AND THEIR ENUMERATION WITH CONSERVATION STATUS Rashid, M. E., M. A. Rahman and M. K. Huda Department of Botany, University of Chittagong, Chittagong 4331, Bangladesh Abstract The study aimed at determining the status of occurrence of the orchid treasure of Bangladesh for providing data for Planning National Conservation Strategy and Development of Conservation Management. 54 orchid species are assessed to be presumably lost from the flora of Bangladesh due to environmental degradation and ecosystem depletion. The assessment of their status of occurrence was made based on long term field investigation, collection and identification of orchid taxa; examination and identification of herbarium specimens preserved at CAL, E, K, DACB, DUSH, BFRIH,BCSIRH, HCU; and survey of relevant upto date floristic literature. These species had been recorded from the present Bangladesh territory for more than 50 to 100 years ago, since then no further report of occurrence or collection from elsewhere in Bangladesh is available and could not be located to their recorded localities through field investigations. Of these, 29 species were epiphytic in nature and 25 terrestrial. More than 41% of these taxa are economically very important for their potential medicinal and ornamental values. Enumeration of these orchid taxa is provided with updated nomenclature, bangla name(s) and short annotation with data on habitats, phenology, potential values, recorded locality, global distribution conservation status and list of specimens available in different herbaria. Key words: Orchid species, lost treasure, Bangladesh, conservation status, assessment. INTRODUCTION The orchid species belonging to the family Orchidaceae are represented mostly in the tropical parts of the world by 880 genera and about 26567 species (Cai et al.

    Plant Biodiversity Science, Discovery, and Conservation: Case Studies from Australasia and the Pacific Craig Costion School of Earth and Environmental Sciences Department of Ecology and Evolutionary Biology University of Adelaide Adelaide, SA 5005 Thesis by publication submitted for the degree of Doctor of Philosophy in Ecology and Evolutionary Biology July 2011 ABSTRACT This thesis advances plant biodiversity knowledge in three separate bioregions, Micronesia, the Queensland Wet Tropics, and South Australia. A systematic treatment of the endemic flora of Micronesia is presented for the first time thus advancing alpha taxonomy for the Micronesia-Polynesia biodiversity hotspot region. The recognized species boundaries are used in combination with all known botanical collections as a basis for assessing the degree of threat for the endemic plants of the Palau archipelago located at the western most edge of Micronesia’s Caroline Islands. A preliminary assessment is conducted utilizing the IUCN red list Criteria followed by a new proposed alternative methodology that enables a degree of threat to be established utilizing existing data. Historical records and archaeological evidence are reviewed to establish the minimum extent of deforestation on the islands of Palau since the arrival of humans. This enabled a quantification of population declines of the majority of plants endemic to the archipelago. In the state of South Australia, the importance of establishing concepts of endemism is emphasized even further. A thorough scientific assessment is presented on the state’s proposed biological corridor reserve network. The report highlights the exclusion from the reserve system of one of the state’s most important hotspots of plant endemism that is highly threatened from habitat fragmentation and promotes the use of biodiversity indices to guide conservation priorities in setting up reserve networks.

A total of 493 specimens were collected. They were identified into 273 species, 205 genera and 87 families. These can be categorized into pteridophytes and flowering plants. Among these, 24 species in 17 genera and 12 families are pteridophytes, of which Polypodiaceae is the richest family of 8 species. The remaining species were angiosperms which comprised 170 species of the dicots, and 79 species of the monocots. Among the flowering plants, Orchidaceae was the richest family with 56 species. The second was Labiatae with 11 species in 6 genera while the third was Leguminosae- Caesalpinioideae with 10 species in 5 genera. In addition, six endemic species to Thailand were recorded, i.e., Ardisia ficifolia K.Larsen & C.M.Hu, Ardisia confusa K.Larsen & C.M.Hu, Morinda scabrida Craib, Boesenbergia siamensis (Gagnep.) P.Sirirugsa, Aristolochia kerrii Craib and Magnolia siamensis, Dandy var. siamensis; the latter two species are very rare. The other 4 species, viz. Clematis smilacifolia Wall., Malleola penangiana (Hook.f.) J.J.Sm. & Schltr., Phalaenopsis parishii Rchb.f., and Renanthera coccinea Lour. were also rarely found in this natural habitat. Moreover, there are a number of species which are said to be threatened in Thailand.

  • Orchid Research Newsletter 75 (PDF)
    Orchid Research Newsletter No. 75 January 2020 Editorial Orchids are perhaps not the first thing that comes to mind when we think about climate change. Record temperatures, catastrophic droughts, melting glaciers, out-of- control bush fires, burning rainforests and other calamities are of more immediate concern. But when we focus on orchid conservation, it is obvious that climate change looms large. It seems likely that orchids are more vulnerable to climate change than most other plant groups, for the following reasons: (1). Since about 70% of all orchids are epiphytes, they are probably more likely to be affected by drought. Even if mature plants would be able to survive unusually severe droughts, one can imagine that seedlings would be much more vulnerable. If such droughts become too frequent, seedling recruitment will be compromised, and the orchids will die out. (2). Since all orchids go through a mycoheterotrophic stage, at least as as seedlings, they depend on the presence of the right fungi for their long-term survival. It could be that climate change affects these fungi in such a way that they are no longer available to particular orchid species. These will then gradually disappear from their habitats. (3). Similarly, since many orchids depend on highly specific pollinators, the effect of climate change on the availability of these pollinators may be significant. A chain is only as strong as its weakest link, and we do not know if it is the orchid, the fungus or the pollinator that is the weakest link. (4). Orchids tend to occur in sparse, widely dispersed populations.
